 ### The string to parse  
- The <xref:System.DateTime.Parse%2A> method tries to convert the string representation of a date and time value to its <xref:System.DateTime> equivalent. It tries to parse the input string completely without throwing a <xref:System.FormatException> exception.  The string is parsed using formatting information in the current <xref:System.Globalization.DateTimeFormatInfo> object, which is supplied implicitly by the current thread culture.
+ The <xref:System.DateTime.Parse%2A> method tries to convert the string representation of a date and time value to its <xref:System.DateTime> equivalent.

 > [!IMPORTANT]
 >  If the parsing operation fails because of an unrecognized string format, the <xref:System.DateTime.Parse%2A> method throws a <xref:System.FormatException>, whereas the <xref:System.DateTime.TryParse%2A> method returns `false`. Because exception handling can be expensive, you should use <xref:System.DateTime.Parse%2A> when the parsing operation is expected to succeed because the input source is trusted. <xref:System.DateTime.TryParse%2A> is preferable when parsing failures are likely, particularly because an input source is not trusted, or you have reasonable default values to substitute for strings that do not parse successfully.
